Greetings,

Having K PRBs ( resources ) and U Users ( UE ) in LTE SC-FDMA multicell uplink system one can construct matrix of metrics ( SE, SINR ) - M with dimensions U on K. Assume K = U so the M is a square matrix. The objective is to allocate for each user - matrix row ( UE ) PRB with maximal matrix value ( metric ) ( column ). For that Round Robin, 2D-Greedy, Mean Enhanced Greedy ( MEG ), Mean Greedy ( MG ), Simplified Mean Enhanced Greedy ( SMEG ), Hungarian ( Munkres ) algorithms are used, as well as First Maximum Expansion ( FME ), Recursive Maximum Expansion ( RME ), Search-Tree Based Algorithm ( STBA ), Minimium Area Difference ( MAD ), Minimium Area Difference to the envelope ( MADe ), Search-Tree Based Packet Scheduling ( STBPS ), Modified First Maximum Enhanced Greedy ( MFMEG ),Improved Recursive Maximum Expansion ( IRME ), Improved Tree-based Recursive Maximum Expansion ( ITRME ) are used to find optimal and suboptimal assignment of each UE to PRB, by traversing and considering the matrix M. I already have implementation of Hungarian,MEG,MG,SMEG algorithms in matlab ( part of the algs. are unique that couldn't be found anywhere on the web ), besides by asking me very well. Now I need also the rest of algorithms to implement in matalb. Starting from FME,RME,MADE. Does anybody have matlab code or pseudocode or good idea to start how to implement FME ( First Maximum Expansion ) schdeduling ( dynamic ) algorithm ( known also as resources scheduling/allocation problem )? I need the matlab code for the algorithm. Thanks in advance for you help.
